I've done this rendering in 3ds max 2012 using Vray renderer 2.0...the output is carried out on a medium quality..yet some portions of my render are a bit noisy..if any one can suggest me how to irradicate that..also if u could find any other flaws in my render then do suggest me ...!!
thank you!

And set the Noise Treshold below 0.001 or lower for noise free sampling. The lower the value the less noise you get, but it will also increase render time considerably. But the treshold value is the only thing you need to control as all glossy effects answer to the DMC settings globally.

Min Subdivs 1
Max Subdivs 100
Adaptive Amount 1.0

Actually no, it all depends on the Noise Threshold value and the amount of contrast in individual image features. The higher the contrast the more samples. But if the Max Sub value is too low there won't be enough additional samples even if you set the Noise Threshold to 0.001 or lower. It is the beauty of adaptive sampling, it put samples where they are needed.

But in general, all monte-carlo based renderings will take long time to get noise free, especially for blurry effects, but in the Vray DMC algorithm makes it adaptive, which helps quite a bit. Try use the Embree plugin and see if it can speed things up a bit.
